Or how about a battery from a small UPS. Those are cheap on ebay as well. Only problem is weight
Question also:
What has proven to be the best option for smart charger for SLA batteries
When I built my Optronics/MR16 system, I popped open an APC UPS I had just lying around. (Plugged in of course, to keep the battery from dying.) I peeled off the sticker APC put over the original battery manufacturer's labeling and found out it was a 7AH 12V battery - exactly what I wanted. It rides in my rack trunk and I just throw it back in the UPS to charge it. When I get a bit more cash I might get a different charger just for the convenience, but at the moment I'm recovering from gearing up to commute. Ouch. >.<
